Answer:
9 1/3, 12 1/2, 14 3/4
Step-by-step explanation:
I assume the formula you’re working with is A=b*h since nothing says otherwise...
((Patio 1))
So you have your area (147) and your base (15 3/4), now you need to plug them in, which should look like this:
147= 15 3/4*h
You need to isolate your h in order to get the missing number, so you should divide both sides by 15 3/4 OR 63/4 ((15*3—>60+3=63))
Dividing by a fraction is the equivalent of multiplying by its reciprocal... so
147 * 4/63 = 588/63 which can be simplified to 84/9 once both the numerator and denominator are divided by 7
In mixed number for it is 9 3/9 which simplified becomes 9 1/3
You solve the other similarly

How many cans will kyra be able to make from the sheet of metal
Answers
Kyra will make 9 cans from the sheet of metal.
Solution:
Height of the can (h) = 5 in
Radius of the can (r) = 6 in
The can is in the shape of a cylinder.
Surface area of the cylinder = [tex]2 \pi r^{2}+2 \pi r h[/tex]
Surface area of the can = [tex]2 \times3.14 \times 6^{2}+2 \times 3.14 \times 6\times 5[/tex]
[tex]$=226.08+ 188.57[/tex]
[tex]=414.65[/tex]
Surface area of the can = 414. 65 in²
Area of sheet of metal = 3750 in²
To find how many cans able to make:
[tex]$\text { Number of cans} =\frac{\text { Area of sheet metal }}{\text { Surface area of the can }}[/tex]
[tex]$=\frac{3750}{414.65}[/tex]
= 9.04
Number of cans = 9
Hence Kyra will make 9 cans from the sheet of metal.

Answers
Step-by-step explanation:
[tex]50 \geqslant 15x \\ \\ \implies \: \frac{50}{15} \geqslant x\\ \\ \implies \: \frac{10}{3} \geqslant x \\ \\ \therefore \: x \leqslant \frac{10}{3} \\ thus \: \{x \: | \: x \leqslant \frac{10}{3} \} \: is \: the \: correct \: \\ solution \: set.[/tex]
The correct solution set of 50 ≥ 15x is {x | x ≤ 10/3 }.\
What is an inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
Given that the expression;
50 ≥ 15x
We can add subtract the 15x - 50 of both sides,
⇒50 - 15x - 50 ≥ 15x -15x - 50
⇒50 - 15x - 50 ≥ 15x -15x - 50
⇒ - 15x ≥ - 50
Now we multiply by -1 ,after this process inequality symbol must be reversed
⇒ 15x ≤ 50
Divide by 50 on both sides,
⇒ 15x / 50 ≤ 50 / 50
⇒ 3x/10 ≤ 1
⇒ x ≤ 10 /3
Therefore, the solution set is {x | x ≤ 10/3 }

Which expression is equivalent to 9a1/2b14c3/2?
Answers
The given algebraic expression 9a1/2b14c3/2 appears to be a kind of factorization where a, b, c are variables raised to different powers. Unless values for these variables are provided, this expression can't be simplified further.
Explanation:The expression 9a1/2b14c3/2 is considered as a form of factorization in mathematics where a, b, c denote variables, and the numbers 1/2, 14, 3/2 are their respective exponents. In other words, it's a product of the variables 'a', 'b', and 'c' raised to their respective powers. For instance, 'a' is under a square root (as signified by the power of 1/2), 'b' is raised to the power of 14, and 'c' is also under a square root but cubed (a power of 3/2).
Consequently, this expression doesn't seem to have a simpler or equivalent expression because the terms 'a', 'b', and 'c' are likely representing different entities, hence they can't be combined or simplified further. However, should there be values for 'a', 'b', and 'c', it's simply substituted into the expression and calculated accordingly.

U and V are mutually exclusive events. P(U) = 0.27; P(V) = 0.56. Find:
P(U and V) =
b. P(U|V) =
c. P(U or V) =
Answers
Answer:
(a) P (U and V) = 0.
(b) P (U|V) = 0.
(c) P (U or V) = 0.83.
Step-by-step explanation:
Mutually exclusive events are those events that cannot occur at the same time. That is, if events A and B are mutually exclusive then,
[tex]P (A\cap B) = 0[/tex]
Given:
Events U and V are mutually exclusive.
P (U) = 0.27 and P (V) = 0.56
(a)
As events U and V are mutually exclusive, the probability of their intersection will be 0.
That is,
[tex]P(U\ and\ V) = P (U\cap V) = 0[/tex]
Thus, the value of P (U and V) is 0.
(b)
The conditional probability of event B given A is:
[tex]P(B|A) =\frac{P(A\cap B)}{P(B)}[/tex]
Compute the value of P (U|V) as follows:
[tex]P(U|V) =\frac{P(U\cap V)}{P(V)}\\=\frac{0}{0.56}\\ =0[/tex]
Thus, the value of P (U|V) is 0.
(c)
The probability of the union of two events, say A and B, is
[tex]P(A\ or\ B)=P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]
Compute the value of P (U or V) as follows:
[tex]P(U\ or\ V)=P(U\cup V)\\=P(U)+P(V)-P(U\cap V)\\=0.27+0.56-0\\=0.83[/tex]
Thus, the value of P (U or V) is 0.83.
The events U and V are mutually exclusive. So, the value of P(U and V) is 0, the value of P(U|V) is 0, and the value of P(U or V) is 0.83 and this can be determined by using the given data.
Given :
P(U) = 0.27P(V) = 0.56U and V are mutually exclusive events.A) P(U and V)
P(U and V) = P(U [tex]\cap[/tex] V) = 0
Because U and V are mutually exclusive events.
B) P(U|V)
[tex]\rm P(U|V) = \dfrac{P(U\cap V)}{P(V)}[/tex]
[tex]\rm P(U|V) = \dfrac{0}{0.56}[/tex]
P(U|V) = 0
C) P(U or V)
[tex]\rm P(U \;or\;V) = P(U\cup V)[/tex]
[tex]\rm P(U \;or\;V) = P(U)+P(V)-P(U\cap V)[/tex]
P(U or V) = 0.27 + 0.56 - 0
P(U or V) = 0.83
The events U and V are mutually exclusive. So, the value of P(U and V) is 0, the value of P(U|V) is 0, and the value of P(U or V) is 0.83 and this can be determined by using the given data.

what is the solution to the following system?
Answers
Answer:
Option C: (2, 1, 0)
Step-by-step explanation:
We are given a system of three equations. Usually, we eliminate a variable from the equations. Solve for the remaining two equations and determine the value of the third equation later.
Here, we are given the choices. So, we can readily substitute each option in the equations. The solution should satisfy all the three equations.
Option A: (3, 1, 0)
Equation (1): 3x + 3y + 6z = 9
⇒ 3(3) + 3(1) + 6(0) = 9 + 3 ≠ 9
Option A does not satisfy the first equation. So, it is eliminated.
Option B: (0, 1, 0)
Substituting in the first equation: 3x + 3y + 6z = 9
⇒ 3(0) + 3(1) + 6(0) = 3 ≠ 9
Option B does not satisfy as well. Hence, it is eliminated.
Option C: (2, 1, 0)
Substituting in 3x + 3y + 6z = 9
⇒ 3(2) + 3(1) + 6(0) = 9
It satisfies Equation 1. For this to be a solution, it should satisfy all the three equations. So, we check for equation 2 and 3.
Equation 2: x + 3y + 2z = 5
2 + 3(1) + 2(0) = 2 + 3 = 5
Equation 3: 3x + 12y + 12z = 18
3(2) + 12(1) + 12(0) = 6 + 12 = 18
Option C satisfies all the equations. So, it is the solution to the system.
On simple substitution, Option D can be eliminated as well.
Hence, the answer.

you can buy popcorn at the village theater in small, medium, or large sizes. the pop corn can be buttered or plain. if all the choices are equally likely, what is the probability that a customer chooses a medium size with butter
Answers
Answer:
Step-by-step explanation:
Close to none because they are all the same price
The probability of a customer choosing a medium size popcorn with butter is 1/6, or about 16.67%.
To find the probability that a customer chooses a medium size popcorn with butter from the Village Theater, we need to consider the total number of possible outcomes and the number of favorable outcomes. Given there are small, medium, and large sizes, and each can be buttered or plain, there are 3 sizes imes 2 types (buttered or plain), which results in 6 total possible outcomes. The event of choosing a medium size with butter is just one of these possible configurations.
Probability of choosing a medium size with butter = Number of favorable outcomes / Total number of possible outcomes = 1 / 6
The chance is 16.67%, which is the decimal 1/6 expressed as a percentage.

How do you convert fraction to percent
Answers
Answer: dividing
Step-by-step explanation:
Final answer:
To convert a fraction to a percent, divide the numerator by the denominator to get a decimal, multiply the decimal by 100, and then add the percent symbol (%).
Explanation:
To convert a fraction to a percent, you start by converting the fraction into a decimal. To do this, divide the numerator (the top number) by the denominator (the bottom number). Once you have the decimal, you multiply it by 100 to get the percent value. Finally, append the percent symbol (%) to the number.
Example:
For the fraction 3/4, first convert it to decimal:
Divide 3 by 4 to get 0.75.Multiply 0.75 by 100, which equals 75.So, 3/4 as a percent is 75%.Another way to convert fractions to percent is by finding an equivalent fraction that has 100 as its denominator. Then, simply use the numerator as the percent. If the fraction's denominator is not easily scalable to 100, it is easier to use the decimal method described previously.

Which system of equations below has exactly one solution?
y=-8x - 6 and y = –8x + 6
y=-8x - 6 and 1/2y = -4x - 3
y=-8x - 6 and y = 8x - 6
y = -8x - 6 and -y = 8x + 6
Answers
Answer:
(y = -8x - 6 and y = 8x - 6) will have exactly one solution.
Step-by-step explanation:
1) Check number of solutions for A (using substitution)
y = -8x -6
y = -8x + 6
-8x - 6 = -8x + 6
+8x +8x
0 - 6 = 0 + 6
-6 = 6 (since this is false, it would be no solution)
2) Check number of sultions for B (using substition)
y = -8x - 6
1/2y = -4x -3
y = -8x - 6 (Multiply both sides of second equation by 2 to cancel out fraction on left side)
-8x - 6 = -8x - 6
Since this is the same equation on both sides- when you cancel everything out it will be 0=0, meaning infinite solution
3) Check number of solutions for C (using substition)
y = -8x - 6
y = 8x - 6
-8x - 6 = 8x - 6
+8x +6 = +8x +6
0 = 16x
x=0
The X value for the solution is 0, when we plug in this X value into one of the equations and solve for Y we will be able to get the Y coordinate
y = -8(0) - 6
y = -6
The solution for C will by (0,-6) which is one solution.
4) Check number of solutions for D (using substition)
y = -8x - 6
-y = 8x +6 --> y = -8x -6
muiltiply both sides of second equation by -1 to make the y positive
-8x - 6 = -8x - 6
Since this is the same equation on both sides- when you cancel everything out it will be 0=0, meaning infinite solution

Step-by-step explanation:
Since FG and HI are parallel and BC is a transversal, then
∠ GBE and ∠ GBE are same side interior angles and are supplementary, thus
3x + 20 + x = 180, that is
4x + 20 = 180 ( subtract 20 from both sides )
4x = 160 ( divide both sides by 4 )
x = 40
